BALING-PRESS.

Specification of Letters Patent.

Application led January 7, 1909.

Patented May 3, 1910.

Serial No. 471,192.

To all whom it may concern:

Be it known that I, JACOB BARnNs, citizen of the United States, residingat Altus, in the county of Franklin and State of Arkansas, have inventedcertain new and useful Improvements in Baling Presses, of which thefollowing is a specification.

The purpose of this invention is to devise novel and effective means foroperating the plunger of baling presses, the actuating means being suchas to enable power to be effectively applied proportionate to thecompression of the bale.

A further purpose of the invention is to supply operating means whichmay be actuated by horse power by a direct pull7 a pair of toggle linksbeing employed, and means cooperating therewith to aline the links asthe material is compressed in the baling chamber with the result thatforce is effectively utilized to the best possible advantage.

For a full understanding of the invention and the merits thereof andalso to acquire a knowledge of the details of construction and the meansfor effecting the result reference is to be had to the followingdescription and accompanying drawings, in which:

Figure 1 is a side elevation of a baling press embodying the inventionshowing the normal position of the parts; Fig. 2 is a top plan view;Fig. 3 is a view similar to Fig. 1 showing the relation of the partswhen the plunger has been -advanced to compress the bale; and, Fig. 4 isa view similar to Figs.

1 and 3 showing the relation of the parts when the plunger is at thelimit of its forward stroke.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The baling chamber 1 may be of any construction and 2 designates theplun er arranged to operate therein. Toggle inks 3 and 4- are pivoted toeach other at 5 and to the plunger and framework ofthe press at 6 and 7respectively. The toggle link 4 is provided with an angularv ordeflected portion near its pivotal connection with the framework and isprovided with a pulley S'near the point of deflection to receive anoperating chain or cable 9. One end of a coil spring 10 is connected tothe toggle links at the joint 5 while the opposite end thereof issuitably connected to a support, such as a bowed standard 11.

The purpose of the spring 10 is to return the parts to normal positionafter the plunger has been advanced to the limit-of its movement. A bullwheel 12 is mounted, upon the framework of the press and may be of anydiameter and has a draft chain or cable connected thereto for attachmento-f the horse by means of which the bull wheel is turned when the pressis in operation. A cam 14 is provided upon one side of the bull wheeland the draft chain or cable 9 is connected at one end to the outer endthereof. The cam 14 like the periphery of the bull wheel is grooved toprovide a seat to receive the draft chains or'cables 9 and 13, so as toprevent lateralv displacement thereof. The cam 14 has an approximateradial arrangement, its inner end curving about the center of the bullwheel, so as to produce a gradual and effective pressure when giving thefinal movement to the plunger upon its forward stroke. One end of thedraft chain or cable 9 is attached to a trolley 15 mounted to travelupon the toggle link 4, whereby the point of application of the powergradually approaches the joint 5 as the links 3 and 4 are brought intoaline-ment iii the operation of the press. A guide pulley 16 is appliedto the framework of the press and the draft chain or cable 9passestherearound. The

guide pulley 16 is located a distance from the pivot connection 7 of thetoggle link 4 with the framework slightly less than the length of thetoggle link 4, so that when the toggle links 3 and 4 are in alinementthe trolley 15 will occupy a position correspondving approximately tothe joint 5 between the toggle lin-ks 3 and 4. This arrangement insuresthe most effective application of power.

In the normal position of the parts the toggle link 4 standsapproximately vertical and after the baling chamber has received acharge of material. to be compressed, the horse attached to the draftchain or cable 13 is drivenforward thereby turning the bull wheel 12 andimparting movement tothe cam 14, which exerts a pull upon the draftchain or'cable 9 with the result that the toggle link 4 is moved fromthe vertical position and the plunger 2 advances in the baling chamber.As the resistance to the forward movement-of the plunger increases thelever-l age proportionately increases, first,fby theI action o the cam14, secondly, by the ower of the toggle links 3 and4, and thir ly, by

the movement of the trolley l5 upon the toggle links 4 toward the joint5. Whenfthe plunger is advanced to the limit of its movement the togglelinks 3 and-4 aline and upon permitting the. lhorse to back the springil() comes into play and returns theparts to normal position. In theoperation of the press the horse is alternately driven" forwardfandthenbaoked,the-force being applied by a= di'- rect pull and the poweraugmented by the combined? action.- of the camy 14", the toggle linksandthe movement of the drai't chainor cable-Q'upon the toggle link 4;From the foregoing it will be understood that the invention provides apress operating means which is both simple and effective and whichenables direct application of draft in a straight line and by a directpull', the parts being'.` so arranged as toproportionately increasethepower as the compression of the bale increases, thereby enabling thepull' to be practically steady vand uniform.-

Having thus described the inventionl what is claimedv as new is:
